Description

Verfahren zum Reinigen von Gasen mittels elektrischen Feldes. Während es verhältnismäßig leicht ist, aus verunreinigten Gasen die Beimengungen bis zu einem gewissen Grade zu entfernen, ist es sehr schwer, den letzten Rest der Verunreinigungen zu beseitigen. Beispielsweise kann Hochofengas, das 5 g pro Kubikmeter Verunreinigungen enthält, verhältnismäßig leicht bis auf 0,5 g/cbm gereinigt -werden. Dagegen ist es sehr schwer, den Gehalt an Verunreinigungen weiter bis auf den Betrag von o,- g/cbm herabzusetzen, wie es erforderlich ist für die Ausnutzung der Gase in der Gasmaschine.Process for cleaning gases by means of an electric field. While it is relatively easy to remove the impurities to some extent from polluted gases, it is very difficult to remove the last remainder of the impurities. For example, blast furnace gas, which contains 5 g per cubic meter of impurities, can be cleaned relatively easily down to 0.5 g / cbm. On the other hand, it is very difficult to further reduce the content of impurities down to the amount of o, - g / cbm, as is necessary for the utilization of the gases in the gas engine.

Gemäß der Erfindung wird- das Gas mit den üblichen Mitteln zunächst vorgereinigt, beispielsweise bis auf 0,5 gIcbm. Es kann dies beispielsweise geschehen, indem es durch ein Elektrodensystem von bekannten Abmessungen und bekannter Feldstärke geleitet wird.According to the invention, the gas is initially used by the usual means pre-cleaned, for example down to 0.5 gIcbm. This can happen, for example, by passing through an electrode system of known dimensions and known field strength is directed.

Der Elektrodenabstand ist hierbei weit größer als r cm, so daß die angelegte Feldstärke auf etwa 2o ooo Volt pro Zentimeter begrenzt ist, weil bei derartigen Elektrodenabständen mit höheren Feldstärken Funkenüberschläge eintreten.The distance between the electrodes is far greater than r cm, so that the applied field strength is limited to about 20,000 volts per centimeter because at Such electrode gaps with higher field strengths can result in arcing.

Das Gas nun, welches so vorgereinigt ist, wird gemäß der Erfindung nochmals und bis zu dem verlangten Grade gereinigt, indem es zwischen Elektroden hindurchgeleitet wird, deren Abstand nur wenige Millimeter bis höchstens s cm beträgt, gemäß dem bekannten Gesetz, daß zwischen Elektroden von so geringem Abstand eine bedeutend höhere Spannung erforderlich ist, ehe Funkenüberschläge eintreten.The gas, which has been pre-cleaned in this way, is according to the invention cleaned again and to the extent required by placing it between electrodes is passed through, the distance between which is only a few millimeters to a maximum of s cm, according to the well-known law that between electrodes of such a small distance one significantly higher voltage is required before arcing occurs.
